Pothos Leaves Turning Yellow: Causes and Remedies

Yellowing leaves on your pothos plant can be a concerning sight, especially if you're new to indoor gardening. It's not uncommon to see some leaves turn yellow, but if it's happening consistently, then there may be something wrong. In this article, we'll explore the reasons behind pothos leaves turning yellow and how to fix them.

1. Overwatering

One of the most common reasons for yellowing pothos leaves is overwatering. Pothos plants prefer slightly moist soil, but too much water can lead to root rot, which can cause the leaves to turn yellow and fall off. To avoid overwatering your pothos plant, make sure to water it only when the top inch of soil feels dry.

If you suspect that overwatering is causing the yellowing leaves, reduce the frequency of watering and make sure the drainage in the pot is functioning correctly. If the plant is sitting in a saucer filled with water, remove the excess water after 30 minutes to prevent the soil from becoming waterlogged.

2. Underwatering

On the other hand, if your pothos leaves are turning yellow and crispy, it might be a sign of underwatering. Pothos plants require regular and adequate watering to stay healthy. If you forget to water your plant or wait until the soil dries out completely, the leaves will start to turn yellow and eventually fall off.

To remedy the situation, water your pothos plant thoroughly until the water comes out of the drainage holes at the bottom of the pot. Do this once a week or whenever the soil feels dry to the touch.

3. Fertilizer Issues

Another reason why pothos leaves turn yellow is due to fertilizer issues. Over-fertilizing or using the wrong type of fertilizer can lead to nutrient burn, which causes the leaves to turn yellow, brown, and crispy.

If you suspect that fertilizer is causing the yellowing leaves, reduce the frequency of fertilizing and use a balanced liquid fertilizer that contains equal amounts of nitrogen, phosphorus, and potassium. Apply the fertilizer every four to six weeks during the growing season, and make sure to dilute it according to the instructions on the label.

4. Pest Infestations

Pests such as spider mites, mealybugs, and scale insects can cause pothos leaves to turn yellow and drop off. These pests suck the sap from the leaves, causing them to wilt and discolor.

If you suspect that pests are causing the yellowing leaves, isolate the affected plant and inspect it closely. You can get rid of the pests by wiping the leaves with a mild soap solution or using a natural insecticide like neem oil. Make sure to repeat the treatment every week until the pests are gone.

5. Environmental Factors

Lastly, environmental factors such as low light, cold drafts, and extreme temperatures can cause pothos leaves to turn yellow. Pothos plants thrive in bright, indirect sunlight and temperatures ranging from 65-85°F (18-29°C).

If your pothos plant is exposed to low light or cold drafts, move it to a brighter and warmer location. Also, make sure to keep the plant away from heating vents or air conditioners, which can cause rapid changes in temperature and humidity.

Indoor Pothos Plant

Pothos leaves turning yellow is a common problem faced by many indoor gardeners. By identifying the cause of the problem and taking appropriate action, you can ensure that your pothos plant remains healthy and vibrant. Some related to pothos plant care include propagation, pruning, repotting, and pest control.
